Oops, thought I also showed passwd:

C:\NCygwin\bin>cat ..\etc\passwd
lemkemch:unused:12729:10513:U-INA-DE01\lemkemch,S-1-5-21-1373454394-1654746546-1846952604-2729:/home/lemkemch:/bin/tcsh

C:\NCygwin\bin>mkpasswd -d | grep -i lemkemch
lemkemch:*:1175788:1049089:XXXXXXXX\lemkemch,S-1-5-21-435809281-806517502-2525237208-127212:/home/lemkemch:/bin/bash

Note that "they" did a domain switch here at some point.  My installation 
is really old and the passwd certainly is from before that domain change.

many many groups I don't like to post here.

I noticed something else: With nsswitch.conf db:

Note the different numerical id's that translate to the same username.
Don't know if it means anything.  I just find it weird.
